Manufacturing FAT and SAT Documentation Management Guide

A Factory Acceptance Test binder is usually thick, thorough, and the last time anyone looks at it. Equipment passes FAT at the vendor's shop, passes SAT once it's installed on site, and then the punch list, the test records, and the vendor documentation get filed away — right as the maintenance team is about to need every page of it. The handover from commissioning to operations is where a lot of asset history quietly disappears before an asset even runs its first production cycle. This guide walks through how to manage FAT and SAT documentation so it survives the handover — punch lists, test records, and commissioning data that actually becomes the asset's maintenance history — using OXMAINT AI, the AI-powered CMMS that turns commissioning records into the first entries in an asset's permanent maintenance record.

Manufacturing FAT and SAT Documentation Management Guide

A punch list item closed out during commissioning, but never logged where maintenance will actually look for it, might as well not have been fixed. OXMAINT AI gives FAT and SAT documentation a permanent home: test records, punch list items, and vendor documentation get logged against the specific asset before it's even running production, open punch list items convert into tracked work orders, and everything closed during commissioning becomes the starting point of that asset's maintenance history — not a binder that gets archived and forgotten.

Where Commissioning Records Actually Go to Die

Nobody loses a FAT binder on purpose. It happens gradually — the project team that ran commissioning moves to the next project, the vendor's documentation lives in an email thread, and the maintenance team inherits a piece of equipment with a maintenance history that technically starts today, even though the machine has already been tested twice. Start free and give your next commissioning project a real record in OXMAINT AI.

COMMISSIONING FILES & BINDERS

Where the History Gets Lost

FAT and SAT reports filed as PDFs, disconnected from the asset's future record
Punch list tracked in a spreadsheet the project team owns, not maintenance
Open items marked "closed" with no record of what was actually done
Vendor documentation and test data live outside the CMMS entirely
Maintenance team starts the asset's history from zero at go-live

FAT/SAT RECORDS IN OXMAINT AI

What a Connected Handover Delivers

FAT and SAT results logged directly against the asset's own record
Punch list items tracked as work orders, owned and followed through
Closed items carry what was actually done, not just a status change
Vendor documentation and test data sit on the same asset the maintenance team will service
Maintenance history starts with everything commissioning already learned

The Commissioning-to-Handover Workflow

FAT, SAT and handover aren't three disconnected events — they're stages of the same asset record. OXMAINT AI carries the same asset through all four steps, so nothing has to be re-entered at the handover point. Book a demo to see this workflow on your next project.

FAT at the Vendor's Shop

Factory Acceptance Test results, deviations, and any punch list items identified before the equipment ships are logged against the asset record you're already setting up for it.

▼

SAT On Site

Site Acceptance Test results are logged against the same asset record, alongside the FAT data — so a reviewer can see whether an issue found at FAT actually got resolved before installation, or carried through.

▼

Punch List Tracked as Work Orders

Each open punch list item becomes a tracked work order with an owner, not a spreadsheet row — so "closed" means someone did the work and it's logged, not just that a box got checked before go-live.

▼

Handover Becomes Maintenance History

At go-live, the maintenance team inherits an asset record that already holds FAT results, SAT results, and every punch list closure — the starting point for PM scheduling and future troubleshooting.

FAT vs. SAT: What Each One Actually Confirms

These two tests answer different questions, and both results matter to the asset's future maintenance history. Sign up free and log both test types against the same asset in OXMAINT AI.

Test	Where it happens	What it confirms
FAT	Vendor's shop, before shipment	Equipment performs to spec in a controlled environment, before it's installed anywhere
SAT	Your site, after installation	Equipment performs correctly connected to your actual utilities, systems and process
Punch list	Generated at either FAT or SAT	Specific open items that need resolution before full acceptance
Handover package	Compiled after SAT sign-off	The complete record maintenance inherits — test data, manuals, punch list closures

A Punch List Item Marked "Closed" Should Mean Something Six Months Later.

When a punch list lives in a spreadsheet the project team owns, "closed" often just means the project moved on. OXMAINT AI keeps every item tied to the asset it belongs to, with a real record of what was done.

One Asset, From FAT to First PM

Here's how a single piece of equipment's record actually builds through OXMAINT AI, start to finish. Book a demo to see this on your own next project.

FAT

A new packaging line's FAT report is logged against the asset record — one minor calibration item flagged for follow-up.

Shipped

Equipment arrives on site — the FAT record and open item travel with the asset record, not a separate file.

SAT

SAT confirms the calibration item was resolved and finds one new punch list item related to site utility connection.

Closed out

The utility connection item is tracked as a work order, assigned, completed, and logged with what was done.

Handed over

Maintenance team inherits the line's full record — FAT, SAT, and punch list closure — as the starting point for its PM schedule.

Binder-Based Handover vs. Connected Asset Record

What matters	Binder / spreadsheet handover	Connected record in OXMAINT AI
Where FAT and SAT data live	Separate files, often per project	Logged against the specific asset
Punch list accountability	Owned by the project team, then handed off	Tracked as work orders with an owner
"Closed" punch list items	Often just a status change	Carries what was actually done
Maintenance team's starting history	Starts from zero at go-live	Inherits FAT, SAT and closure records
Finding a document months later	Depends on who kept the file	On the asset record, searchable

Frequently Asked Questions

Can we start logging FAT data before the equipment is even physically installed?

Yes — an asset record can be created and populated with FAT results before the equipment arrives on site, so SAT data, installation notes, and eventually maintenance history all attach to the same record from day one. Start free and set up your next asset before it ships.

Who should own punch list items after handover — the project team or maintenance?

That depends on the item and your organization's structure, but the key is that ownership is assigned and tracked, not left ambiguous during the handoff between project and operations. An item without a clear owner is the most common way a punch list item quietly never gets closed. Book a demo to see punch list ownership tracking.

Can vendor manuals and technical documentation attach to the asset record too?

Yes — vendor manuals, wiring diagrams, and technical documentation can sit alongside the FAT and SAT records on the same asset, so a technician troubleshooting the equipment later has commissioning data and vendor documentation in one place. Sign up free and attach your own vendor documentation.

How does commissioning data actually help with PM scheduling later?

FAT and SAT often surface baseline readings — calibration values, performance data — that become the reference point for future inspections and PM checks, rather than starting the asset's monitoring program with no baseline at all. Book a demo to see baseline data carried into PM scheduling.

What if commissioning already happened and we're trying to reconstruct the record now?

You can still bring in whatever FAT, SAT, and punch list documentation exists and attach it to the asset retroactively — an incomplete history logged now is still more useful going forward than continuing without any connected record at all. Start free and rebuild your existing asset records.

Give Every New Asset a Maintenance History That Starts Before It Runs.

Log FAT and SAT results against the specific asset, track every punch list item as a real work order, and hand maintenance a record that already knows the equipment — not an empty file at go-live.
